gdr1.phot_variable_time_series_gfov_statistical_parameters

Description

Statistical parameters of field-of-view time series, only including observations with rejected_by_variability_processing=false as found in the phot_variable_time_series_gfov table. Note that only sources that have phot_variable_flag = "VARIABLE" in the gaia_source table are included.

Access

You can access this table using the query interface and download the results afterwards.

The data is stored in a PostgreSQL database system. You can use the query interface to query the tables of the database directly using ADQL or SQL. We also prepared a set of examples for you to get started.

This work has made use of data from the European Space Agency (ESA) mission Gaia, processed by DPAC. Funding for the DPAC has been provided by national institutions, in particular the institutions participating in the Gaia Multilateral Agreement.
